A steam granulation technique involves the injection of a jet of steam into a bed of fludized particles to be granulated. The jet of steam is substantially enveloped by a jet of air to inhibit the premature condensation of the steam onto the fluidized particles and/or the condensation of the steam onto neighboring walls of an apparatus employed to fluidize the particles, thereby inhibiting excessive wetting and lumping of the particles during their granulation.
